COLLAPSIBLE 3011 Application filed. May 23,

This invention relates'to boxes of the type 'in which cloaks and suits are packed for shipment and delivery, and has especial reference to collapsible boxes of this character.

Boxes of the type to which the present invention may be applied consist of two parts or sections, a section which receives the goods or articles, and a section which is the cover for the other section.v Both box parts or sections include walls certain of which have'folds, whereby the walls are collapsed. In that way the box sections are kept'stored in a fiat condition without taking up very much space. It has been found that in use, wallsof these box sections do not stand up, and have a tendency to collapse, allowing unintentionalseparation of the'box sections, and otherwise having a tendency toweaken the boxsections.

It is thereforethe principal object of the present invention to overcome the above mentioned disadvantage by providing collapsible box sections with improved means for releasably maintaining the walls of the box sections in a non-collapsing condition, and for providing additional strength, and rigidity thereto.

The nature of the invention and its distinguishing features and advantages will appear when the following specification is read inconnection with the accompanying drawing, in which- Figure 1 is a perspective View of a box of the collapsible type showing the sections or parts thereof separated from each other.

Fig. 2 is a perspective view of the container or receiving section of the box in a collapsed or folded condition.

Fig. 3 is a sectional view illustrating one of the details.

Referring now more particularly to the views of the drawing for all of the details,

it will be apparent that, the box to which p the present invention is applied consists of two parts or sections, a section 10 and a section 11. The sections 10 and 11 are substantially similar in construction, althorwh thesection 10 is somewhat larger than the section 11 so that the latter may fit within the former. These sections are preferably made of stout cardboard. Inasmuch as both sections 10 and 11 are of similar construction, a description of the structural features of one will serve for both. Use is made of a blank which is cut and formed to provide 1927. semi No. 193,666.

a main fiat wall 12, side walls 13, and end walls 14; the side walls each having at the opposite ends thereof respectively wings 15, cut at an angle as at 16; and each of the end walls 14 has at its opposite ends thereof respectively wings 17 eachof which is cutat an angle as at 18. The side walls 13 and end walls 14 are connected together, and this is accomplished'by folding the wings 15 and 17. respectively on the side and end walls adjacent each other at each corner of the box section, and then'overlapping the said wings. In the overlapped condition each wing 15 will be disposed beside a portion of the related end wall 14 and each Wing 17 \villbe disposed beside a portion. of the relatedside walls 13. The wings are'attached to their related adjacent wall portions by suitable fasteners 19. The wings 15 are only attached along their upper edges which will provide pockets respectively at each corner of the box section. One of the pockets designated 20 is illustrated in Fig. 3.

In order that the side walls 13 and end walls 14 may be folded and then be collapsed over the main flatwall 12, each end wall is scored to provide fold lines 21 which are coincidental with the diagonal edges 16 of the wings 15 respectively. This permits each end wall 14 to be moved or folded over the fiat wall 12, each of said end walls folding on the lines 21, which causes the side walls 13 to be brought over the flat wall 12. there being a folding action at each of the corners or junctures between the side walls and end walls. The folded or collapsed condition of the box section is illustrated in Fig. 2.

In order to support the walls in a non-collapsed condition, and to give strength and rigidity to each of the end walls 14, each of the end, walls 14. is provided with means consisting of a flexible strip 22 whose oposite ends are attached respectively to the wall 14'by suitable fasteners 23, and a stiff or rigid member 24. The said member 24 may advantageously be of wood. The said member 24 is disposed transversely behind the strip 22 and its opposite ends are adapted to enter the pockets 20 respectively on the wall 14, as shown most clearly in Fig. 1. The member 24 is disposed across the fold lines 21 and prevents the end wall from unintentional collapsing. When it is desired to collapse the end wall, it is only necessary to move the member 24 downwardly until the opposite ends thereof are out: of the pockets 20. This may beaccomplished because of the predetermined length of the member 24, and the fact that the wingslli. are cut at an angle. Each of the members 24 will be retained in place by clamping;

and frictional action set up by portions of the end walls and the Wings 15.. -When the top or cover section 10 is arranged over the section 1 1, the side and end walls of the section 10 will receive support -from the braced side and end walls of the section 11; y

It is to be understood that the means for maintaining the walls against collapsing may be applied to either of the sections 150 and 11. or to both of the sections.
